Salts can be easily identified, since they usually consist of positive ions from a metal with negative ions from a non metal. The salt we put on our fries is actually sodium chloride and is made up of metal Na1+ and non metal Cl1- ions. Often you will see this written as Na+ and Cl- (the 1 is dropped) or simply NaCl.
The manufacture of salt is one of the oldest chemical industries. A major source of salt is seawater, which has a salinity of approximately 3.5%. This means that there are about 35 grams (1.2 oz) of dissolved salts, predominantly sodium (Na+) and chloride (Clâ) ions, per kilogram (2.2 lbs) of water.ost of the sodium in the Western diet comes from salt. The habitual salt intake in many Western countries is about 10 g per day, and it is higher than that in many countries in Eastern Europe and Asia. The high level of sodium in many processed foods has a major impact on the total amount consumed.
